## 压缩
```
src:="xrpc"
dst:=fmt.Sprintf("%s.zip",src)
dstFile, err := os.Create(dst)
if err != nil {
log.Fatal(err)
}
defer dstFile.Close()
handle := zip.NewWriter(dstFile)
defer handle.Close()
err = filepath.Walk(src, func(path string, info os.FileInfo, err error) error {
if err != nil {
return err
}
header, err := zip.FileInfoHeader(info)
if err != nil {
return err
}
// 保留层级关系
header.Name=strings.TrimPrefix(path,string(filepath.Separator))
wh, err := handle.CreateHeader(header)
if err != nil {
return err
}
if !info.Mode().IsRegular() {
return nil
}
openFile, err := os.Open(path)
if err != nil {
return err
}
_, err = io.Copy(wh, openFile)
if err != nil {
return err
}
return nil
})
```
## 解压
```
dstDir := "./"
zipReader, err := zip.OpenReader("xrpc.zip")
if err != nil {
log.Fatal(err)
}
defer zipReader.Close()
for _, file := range zipReader.File {
realPath := filepath.Join(dstDir,file.Name)
if file.Mode().IsDir(){
err := os.MkdirAll(realPath, os.ModePerm)
if err != nil {
log.Fatal(err)
}
}else{
create, err := os.Create(realPath)
if err != nil {
log.Fatal(err)
}
open, err := file.Open()
if err != nil {
log.Fatal(err)
}
_, err = io.Copy(create, open)
if err != nil {
log.Fatal(err)
}
}
}
